    OBJECTIVE: Hypogonadism has major effects on the urogenital system, in addition to other systems, the cardiovascular system in particular. There have been few studies conducted on markers of atherosclerosis, such as flow mediated dilatation (% FMD), carotid intima-media thickness (CIMT) and adipocytokine levels in idiopatic hypogonadotropic hypogonadal (IHH) males mostly in adult patients. The aim of this study was to evaluate the relationship between androgens and adipocytokines and parameters of vascular functions in hypogonadal men. MATERIALS AND METHODS: The study population consisted of 11 treatment naive IHH patients (group 1) and 15 age-matched healthy control males (group 2). A fasting blood sample was obtained for leptin, adiponectin and resistin. The endothelial functions were evaluated by studying % FMD and CIMT by high resolution B-mode ultrasound. RESULTS: No significant differences in age, body mass index, systolic and diastolic blood pressure were recorded between the two groups. The leptin level was significantly higher in group 1, whereas adiponectin and resistin levels were same between two groups. There was a negative correlation between total testosterone and carotid intima-media thickness (r=-0.656, p=0.008), and a negative correlation between total testosterone and leptin level (r=-0.794, p<0.001). No correlation was found between leptin and CIMT (p=0.184). CONCLUSION: Testosterone deficiency in hypogonadal men is associated with vascular parameters of atherosclerosis. The findings may establish indications for testosterone replacement therapy in hypogonadal men.

    Non-functioning adrenal incidentalomas are associated with higher hypertension prevalence and higher risk of atherosclerosis

    Introduction Adrenal incidentalomas (AIs) have been associated with an increased incidence of several cardiovascular risk factors. The aim of this study was to investigate plasma adiponectin, leptin, resistin, homocysteine, high sensitive C-reactive protein levels, and carotid intima media thickness (CIMT) in patients with non-functioning AI (NFAI). Materials and methods This study included data from 28 patients with NFAI (Group 1) and 41 controls (Group 2). Of the patients, 50 were female and 19 were male, and the mean age was 46.7 (range 37-65) years. Results There were no significant differences between Group 1 and 2 in terms of age, sex, or BMI. Hypertension prevalence was significantly higher in the NFAI group than in the control group (p = 0.01). Both groups had similar lipid, blood glucose, homocysteine, uric acid, high-sensitivity CRP levels. Adiponectin, leptin, and resistin levels were similar in both groups. CIMTs were significantly higher in the NFAI group. Conclusion There is increasing evidence that several cardiometabolic risk factors occur with higher prevalence in non-functioning adrenal incidentaloma patients compared to age-matched healthy subjects. In our study, hypertension prevalence and CIMT were higher in the NFAI group. Serum adipokine levels were similar for both groups.
